Pragmatic Cluster-Randomised Trial: Efficacy of a Fixed-Dose Polypill in Reducing Cardiovascular Disease Risk in Rural Iran
25 Mar, 2024 | 11:40h | UTCStudy Design and Population: The PolyPars Study was structured as a two-arm pragmatic cluster-randomised trial within the larger PARS cohort study. It targeted residents aged over 50 in a district in southern Iran, dividing 91 villages into two groups: one receiving a once-daily polypill (containing two antihypertensives, a statin, and aspirin) alongside non-pharmacological interventions, and the other receiving only the non-pharmacological interventions. The trial included 4,415 participants aged 50-75 years, with the primary endpoint being the first occurrence of major cardiovascular events.
Main Findings: Over a median follow-up of 4.6 years, adherence to the polypill was high at 86%. The intervention arm showed a significant reduction in the incidence of the primary outcome, with only 4.0% (88 participants) experiencing major cardiovascular events compared to 8.0% (176 participants) in the control arm. This translates to a hazard ratio of 0.50, indicating a 50% reduction in risk, and an absolute risk reduction of 4.0%.
Implications for Practice: The study demonstrates the significant potential of fixed-dose combination therapy with the polypill to halve the risk of major cardiovascular diseases in a population-level intervention. This finding supports the polypill as a safe and effective strategy for both primary and secondary prevention of cardiovascular diseases, particularly in settings where access to individual medications and consistent medical supervision might be limited.

RCT: Free Access to Water vs. Fasting Pre-Cesarean Reduces Vomiting and Increases Maternal Satisfaction
25 Mar, 2024 | 11:17h | UTCStudy Design and Population: This randomized controlled trial was carried out at the Obstetric Unit, Universiti Malaya Medical Center from October 2020 to May 2022. A total of 504 women scheduled for planned cesarean delivery under spinal anesthesia were randomized into two groups: 252 were allowed free access to water up until being called to the operating theater, and 252 were required to fast from midnight before the procedure. The study primarily aimed to evaluate the effects of these preoperative oral intake policies on perioperative vomiting and maternal satisfaction.
Main Findings: The results demonstrated significant benefits for the group with free access to water. Specifically, perioperative vomiting was observed in 3.6% of women with water access compared to 9.5% of those fasting, indicating a relative risk reduction. Maternal satisfaction scores were notably higher in the water access group, with median scores of 9 versus 5 for the fasting group. Additional findings included lower reports of thirst, fewer instances of preoperative intravenous hydration, reduced ketone presence in urine, and a lower average number of vasopressor doses needed. Significantly, 95.2% of participants in the water access group would recommend their regimen to a friend, compared to only 39.7% in the fasting group.
Implications for Practice: Allowing free access to water up until the time of surgery for women scheduled for cesarean delivery under spinal anesthesia significantly reduces the risk of perioperative vomiting and improves maternal satisfaction, without adversely affecting post-cesarean recovery or neonatal outcomes. These findings support revising current preoperative fasting guidelines to improve patient experience and potentially enhance clinical outcomes.

Nested Case-Control Study: Increased risk of major bleeding in atrial fibrillation patients with concomitant SSRI and oral anticoagulant use
23 Mar, 2024 | 20:48h | UTCStudy Design and Population
This nested case-control study investigated the association between the concomitant use of selective serotonin reuptake inhibitors (SSRIs) and oral anticoagulants (OACs) on the risk of major bleeding among patients with atrial fibrillation. Conducted within the UK’s Clinical Practice Research Datalink, the study included 42,190 cases of major bleeding matched to 1,156,641 controls based on age, sex, cohort entry date, and follow-up duration. Patients initiating OACs between January 2, 1998, and March 29, 2021, were included, with risk-set sampling utilized for control selection.
Main Findings
The study found that concomitant use of SSRIs and OACs was associated with a 33% increased risk of major bleeding compared to OAC use alone, with the highest risk observed within the first 30 days of concurrent use. The increased risk was consistent across different ages, sexes, and patient histories, including those with chronic kidney disease or previous bleeding events. Notably, the elevated risk of bleeding extended up to 6 months of concomitant use but did not vary significantly with the potency of SSRIs or the type of OAC used (direct OACs or vitamin K antagonists).
Implications for Practice
These findings underscore the need for healthcare professionals to closely monitor patients with atrial fibrillation who are prescribed SSRIs in addition to OACs, particularly during the initial months of treatment. This study highlights the importance of managing bleeding risk factors and suggests reconsidering the necessity and duration of concomitant SSRI and OAC use. Future research should focus on strategies to mitigate this bleeding risk and explore alternative treatments for managing depression in patients requiring anticoagulation.

RCT: Clarithromycin improves early clinical and inflammatory responses in hospitalized community-acquired pneumonia patients
23 Mar, 2024 | 20:25h | UTCStudy Design and Population: The ACCESS trial was a phase 3, prospective, double-blind, randomized controlled trial conducted in 18 Greek hospitals, involving adults hospitalized with community-acquired pneumonia who displayed systemic inflammatory response syndrome, had a Sequential Organ Failure Assessment (SOFA) score of 2 or more, and procalcitonin levels of 0.25 ng/mL or more. Participants were randomly assigned to receive either standard of care with intravenous cephalosporins or β-lactam/β-lactamase inhibitor combinations plus oral clarithromycin (500 mg twice daily for 7 days) or placebo. The trial aimed to evaluate the impact of clarithromycin on early clinical and inflammatory responses.
Main Findings: Among 278 participants allocated to clarithromycin (n=139) or placebo (n=139), the primary composite endpoint—indicating early clinical response and inflammatory burden reduction within 72 hours—was met by 68% of patients in the clarithromycin group compared to 38% in the placebo group, showcasing a significant difference (29.6%, odds ratio 3.40, p<0.0001). Serious treatment-emergent adverse events were slightly lower in the clarithromycin group than in the placebo group, although not statistically significant.
Implications for Practice: The addition of clarithromycin to the standard of care for hospitalized patients with community-acquired pneumonia significantly improves early clinical response and reduces inflammatory burden, potentially through modulation of the immune response. These results support the use of clarithromycin alongside β-lactam antibiotics in the treatment of community-acquired pneumonia, highlighting its role in enhancing patient outcomes by targeting early clinical and inflammatory indicators.

Observational Study: Association of antiarrhythmic drug use with increased risk of pacemaker implantation and syncope in new-onset atrial fibrillation patients
23 Mar, 2024 | 20:08h | UTCStudy Design and Population
This observational study utilized data from the Korean National Health Insurance Service to evaluate the impact of antiarrhythmic drugs (AADs) on the risk of pacemaker implantation or syncope in patients diagnosed with new-onset atrial fibrillation (AF) between 2013 and 2019. A total of 770,977 new-onset AF cases were identified, with 142,141 patients prescribed AADs within one year of diagnosis. The study compared the risk of these outcomes between AAD users and nonusers.
Main Findings
The study found that the use of AADs was associated with a significantly increased risk of pacemaker implantation or syncope, with adjusted risks being 3.5 times higher for either outcome, 2.0 times higher for syncope alone, and 5.0 times higher for pacemaker implantation. These associations were consistent across various patient subgroups, and propensity score-matched analysis supported these findings. Notably, women were found to be more susceptible to the adverse effects of AADs than men.
Implications for Practice
The findings suggest a need for careful evaluation of the risks associated with AAD use in patients with new-onset AF, particularly regarding the potential for pacemaker implantation or syncope. These results highlight the importance of individualized patient assessment before prescribing AADs to mitigate these risks effectively. Further research is needed to explore the mechanisms behind these associations and to develop strategies to minimize adverse outcomes in this patient population.

PCI vs. CABG in left main coronary disease patients with and without diabetes—a pooled analysis of 4 trials
22 Mar, 2024 | 11:41h | UTCStudy Design and Population: This research pooled individual patient data from four randomized clinical trials (SYNTAX, PRECOMBAT, NOBLE, and EXCEL), comparing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in 4393 patients with left main coronary artery disease. The trials included both patients with and without diabetes, allowing for a comparative analysis of outcomes based on the revascularization method and the presence of diabetes.
Main Findings: Patients with diabetes exhibited higher rates of 5-year mortality, spontaneous myocardial infarction (MI), and repeat revascularization compared to those without diabetes. However, mortality rates following PCI vs. CABG were similar in diabetic (15.3% vs. 14.1%, respectively) and non-diabetic patients (9.7% vs. 8.9%, respectively). PCI was associated with a lower risk of stroke within the first year post-operation across all patients. Notably, diabetic patients underwent higher rates of spontaneous MI and repeat revascularization after PCI compared to CABG, with a more significant absolute excess risk observed beyond the first year compared to non-diabetic patients.
Implications for Practice: For patients with left main disease deemed suitable for either PCI or CABG, diabetes status significantly influences long-term outcomes, including death and cardiovascular events. While PCI offers a lower early risk of stroke, it is associated with increased risks of spontaneous MI and repeat revascularization, particularly in diabetic patients. These findings underscore the importance of considering patient-specific factors, such as diabetes status, in choosing between PCI and CABG for left main coronary artery disease revascularization.

Cohort Study: The impact of rare kidney diseases on kidney failure and survival rates in the UK’s RaDaR cohort
22 Mar, 2024 | 11:29h | UTCStudy Design and Population: This cohort study utilized data from the UK National Registry of Rare Kidney Diseases (RaDaR), encompassing 27,285 participants aged 0-96 years with 28 types of rare kidney diseases, recruited from 108 renal care facilities across the UK. The primary outcomes assessed were the cumulative incidence of mortality and kidney failure, compared with those of a general population with chronic kidney disease (CKD).
Main Findings: Over a median follow-up of 9.6 years, participants with rare kidney diseases exhibited a significantly higher 5-year cumulative incidence of kidney failure (28%) compared to the broader UK CKD population (1%, p<0.0001). However, they also showed better survival rates, with a standardized mortality ratio of 0.42. There was considerable variability in median ages at kidney failure and death, time from dialysis start to death, and time from diagnosis to reaching specific eGFR thresholds among different rare diseases.
Implications for Practice: This study highlights the distinct trajectory of rare kidney diseases compared to more common forms of CKD, with higher rates of kidney failure but improved survival outcomes. These findings emphasize the over-representation of patients with rare kidney diseases in kidney replacement therapy cohorts and underscore the urgent need for targeted therapeutic interventions. Addressing this unmet need could significantly reduce the demand for long-term kidney replacement therapy, benefiting patients and easing healthcare system burdens.

M-A: Cardiovascular benefits of SGLT2 inhibitors in patients without diabetes
22 Mar, 2024 | 11:07h | UTCStudy Design and Population: This meta-analysis investigated the cardiovascular (CV) outcomes associated with sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients without diabetes mellitus (DM). By systematically reviewing online databases, the authors identified and included six randomized controlled trials (RCTs) in their analysis. These trials compared SGLT2i with placebo/control in a total of 12,984 participants, who were followed for an average duration of 17.7 months. The study population comprised mainly patients with heart failure (HF), chronic kidney disease, or myocardial infarction, with a mean age of 64 years, where 72% were men and the mean hemoglobin A1C level was 5.7%.
Main Findings: The use of SGLT2i was associated with a significant reduction in composite CV death or hospitalization for HF, with an odds ratio (OR) of 0.77 (95% confidence interval [CI], 0.68 to 0.87, p < 0.0001), primarily due to a decrease in hospitalization for HF (OR 0.70, 95% CI 0.60 to 0.81, p < 0.00001). No significant differences were observed in CV death, all-cause death, or major adverse CV events when comparing SGLT2i to placebo. Notably, serious adverse events were lower with the use of empagliflozin compared to placebo.
Implications for Practice: This meta-analysis highlights the significant CV benefits of SGLT2i treatment in reducing CV death or hospitalization for HF in patients without DM, compared with placebo. These findings suggest the potential for broader use of SGLT2i in populations without diabetes to improve cardiovascular outcomes.

RCT: Lower oxygenation target improves days alive without life support in severe COVID-19 hypoxemia
21 Mar, 2024 | 13:46h | UTCStudy Design and Population: This multicenter randomized clinical trial investigated the impact of different oxygenation targets on the survival of adult patients with COVID-19 and severe hypoxemia in the ICU. Conducted across 11 European ICUs from August 2020 to March 2023, the study involved 726 patients requiring at least 10 L/min of oxygen or mechanical ventilation. Participants were randomly assigned to receive an oxygenation target of either 60 mm Hg (lower oxygenation group, n=365) or 90 mm Hg (higher oxygenation group, n=361) for up to 90 days.
Main Findings: The primary outcome was the number of days alive without life support at 90 days post-intervention. Patients in the lower oxygenation group achieved a median of 80.0 days alive without life support compared to 72.0 days in the higher oxygenation group, a difference that was statistically significant (P=0.009). Although there was a slight reduction in mortality at 90 days in the lower oxygenation group (30.2% vs 34.7% in the higher group), this was not statistically significant. No significant differences were observed in the proportion of patients with serious adverse events or the number of days alive and out of hospital.
Implications for Practice: Targeting a lower Pao2 of 60 mm Hg in ICU patients with COVID-19 and severe hypoxemia appears to increase the days alive without life support compared to a higher target of 90 mm Hg, without increasing serious adverse events. This finding suggests that a lower oxygenation target could be more beneficial for this patient population, potentially guiding clinical practice in managing oxygen therapy for severe COVID-19 cases.

Cohort Study: Elevated autism spectrum disorder risk in children exposed to valproate during pregnancy
21 Mar, 2024 | 13:16h | UTCStudy Design and Population: This cohort study utilized two health care utilization databases in the United States, covering the period from 2000 to 2020, to investigate the association between prenatal exposure to antiseizure medications and the risk of autism spectrum disorder (ASD) in children. The study compared children exposed to topiramate, valproate, or lamotrigine during the second half of pregnancy to those unexposed to any antiseizure medication, specifically focusing on a population-based cohort of pregnant women and their offspring.
Main Findings: The cumulative incidence of ASD at 8 years of age was found to be higher in children exposed to these medications compared to the general population. Notably, the incidence was 6.2% for children exposed to topiramate, 10.5% for valproate, and 4.1% for lamotrigine among children born to mothers with epilepsy. However, after adjusting for potential confounders, the increased risk of ASD remained significant only for valproate exposure, with a hazard ratio of 2.67, indicating a substantial risk compared to unexposed children. Topiramate and lamotrigine showed no significant increase in risk after adjustment.
Implications for Practice: The findings underscore the importance of carefully considering the risks and benefits of using antiseizure medications during pregnancy. Specifically, valproate should be used with caution, if at all, given its significant association with an increased risk of ASD in offspring. This study supports the need for targeted counseling and monitoring of pregnant women with epilepsy and highlights the necessity for further research to fully understand the neurodevelopmental impact of prenatal exposure to antiseizure medications.

Meta-Analysis: No mortality benefit of early vs. delayed/selective coronary angiography in out-of-hospital cardiac arrest without ST-elevation
21 Mar, 2024 | 11:40h | UTCStudy Design and Population: This article presents a systematic review and meta-analysis of five randomized controlled trials comparing early/immediate versus delayed/selective coronary angiography (CAG) in 1512 patients who experienced out-of-hospital cardiac arrest (OHCA) without ST-segment elevation. The population had a mean age of 67 years, with 26% female and 23% having a prior myocardial infarction. Follow-up duration was at least 30 days across included studies.
Main Findings: The analysis revealed no significant difference in the odds of all-cause death between early/immediate and delayed/selective CAG strategies (Odds Ratio [OR] 1.12, 95% CI 0.91–1.38). Similar results were found for the composite outcome of all-cause death or neurological deficit (OR 1.10, 95% CI 0.89–1.36). Subgroup analysis showed no significant effect modification based on age, initial cardiac rhythm, history of coronary artery disease, the presumed ischemic cause of arrest, or time to return of spontaneous circulation. Interestingly, a trend toward increased odds of death was observed in women receiving early CAG compared to men, although this finding approached but did not reach statistical significance.
Implications for Practice: The findings suggest that for OHCA patients without ST-segment elevation, an early/immediate CAG strategy does not confer a mortality benefit over a delayed/selective approach across major subgroups. Notably, the potential for increased mortality risk in women with early CAG warrants further investigation. Clinicians should consider these results when deciding on the timing of CAG in this patient population, keeping in mind the overall lack of mortality benefit and the nuanced differences among subgroups.

Systematic Analysis: Global Burden and Trends of Nervous System Disorders, 1990–2021
21 Mar, 2024 | 11:10h | UTCStudy Design and Population
This study, a systematic analysis conducted by the Global Burden of Disease Study 2021, aimed to estimate the global, regional, and national health loss attributable to 37 unique nervous system conditions from 1990 to 2021. The researchers estimated mortality, prevalence, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life years (DALYs) across 204 countries. The analysis included morbidity and deaths directly resulting from damage to the central or peripheral nervous system, as well as neurological health loss from conditions where nervous system morbidity is a secondary outcome.
Main Findings
The collective global burden of these nervous system conditions emerged as the leading cause of DALYs in 2021, affecting approximately 3.40 billion individuals (43.1% of the global population) and resulting in 443 million DALYs. Although global DALY counts for these conditions increased by 18.2% from 1990 to 2021, there was a notable decrease in the age-standardised rates of deaths and DALYs by 33.6% and 27.0%, respectively. The conditions contributing most significantly to the age-standardised DALYs were stroke, neonatal encephalopathy, migraine, and Alzheimer’s disease among others.
Implications for Practice
This analysis underscores the critical need for effective prevention, treatment, and rehabilitation strategies for nervous system disorders, which now lead the global disease burden. Highlighting an 18.2% increase in DALY counts over the study period, it calls for heightened public health attention and resource allocation towards these conditions. The findings support the prioritization of nervous system health on the global health agenda and stress the importance of further research into modifiable risk factors and equitable access to care.

ACG Guideline: Management of Acute Pancreatitis
20 Mar, 2024 | 21:49h | UTCThis guideline, crafted by the American College of Gastroenterology, provides essential strategies for managing acute pancreatitis, offering a concise overview of diagnosis, treatment, and prevention recommendations for healthcare professionals. Here is a summary of the key information contained in the document:
- Introduction and Epidemiology: Acute pancreatitis (AP) is one of the most common gastrointestinal diseases leading to hospitalization in the United States, with about 300,000 admissions annually and a cost of over 2.5 billion dollars. The incidence of AP has been increasing annually, although the mortality rate has remained stable due to advancements in management.
- Etiology and Diagnosis: AP is typically caused by gallstones and alcohol consumption. Diagnosis is made based on the presence of two of the following three criteria: characteristic abdominal pain, serum amylase and/or lipase levels more than three times the upper limit of normal, and/or characteristic findings on abdominal imaging.
- Initial Management and Hydration: Initial management emphasizes the importance of moderate to aggressive intravenous hydration, preferably with lactated Ringer’s solution over normal saline, due to its potential benefit in reducing systemic inflammation and preventing complications.
- Nutrition: Patients with mild AP are encouraged to start early oral feeding within 24 to 48 hours as tolerated, preferring a low-fat solid diet over a progressive approach from liquids to solids.
- Management of Complications: The document addresses the management of complications such as pancreatic necrosis, suggesting the use of antibiotics only in cases of infected necrosis and highlighting a preference for minimally invasive methods of debridement and necrosectomy.
- Prevention of Recurrence and Role of ERCP: To prevent recurrences in biliary pancreatitis, cholecystectomy is recommended. In selected cases of acute biliary pancreatitis without cholangitis, medical therapy is preferred over early ERCP.
- Use of Antibiotics: The guidelines discourage the prophylactic use of antibiotics in cases of severe AP without evidence of infection, due to the lack of demonstrated benefit and potential risks.

Meta-Analysis: Effectiveness of therapist-guided remote vs. in-person cognitive behavioral therapy
20 Mar, 2024 | 19:32h | UTCStudy Design and Population: This systematic review and meta-analysis investigated the efficacy of therapist-guided remote cognitive behavioral therapy (CBT) compared to traditional in-person CBT. The authors conducted a comprehensive search across several databases, including MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials, up to July 4, 2023. A total of 54 randomized controlled trials (RCTs) were included, encompassing 5463 adult patients presenting with various clinical conditions. The study meticulously assessed the risk of bias and extracted data using a standardized approach, and outcomes were analyzed using a random-effects model.
Main Findings: The primary analysis focused on patient-important outcomes, comparing the effectiveness of remote and in-person CBT across diverse conditions such as anxiety and related disorders, depressive symptoms, insomnia, chronic pain or fatigue syndromes, body image or eating disorders, tinnitus, alcohol use disorder, and mood and anxiety disorders. The meta-analysis, based on moderate-certainty evidence, found little to no difference in effectiveness between remote and in-person CBT (standardized mean difference [SMD] −0.02, 95% confidence interval −0.12 to 0.07), suggesting that both delivery methods are comparably effective across a range of disorders.
Implications for Practice: The findings indicate that therapist-guided remote CBT is nearly as effective as in-person CBT for treating a variety of mental health and somatic disorders. This supports the potential for remote CBT to significantly increase access to evidence-based care, especially in settings where in-person therapy is not feasible or is limited by geographic, economic, or social barriers. Future research should explore optimizing remote CBT delivery methods to further enhance accessibility and efficacy.

Genetic analysis reveals Lipoprotein(a) is significantly more atherogenic than LDL on a per-particle basis
20 Mar, 2024 | 19:24h | UTCStudy Design and Population: This study utilized genome-wide association studies (GWAS) within the UK Biobank population to examine the atherogenicity of lipoprotein(a) (Lp(a)) compared to low-density lipoprotein (LDL), focusing on their apolipoprotein B (apoB) content. The researchers identified two clusters of single nucleotide polymorphisms (SNPs) associated with mass concentrations of Lp(a) and LDL, comprising 107 and 143 variants, respectively. The sample included subjects from the UK Biobank, allowing for a broad and genetically diverse analysis.
Main Findings: The study’s Mendelian randomization approach found that a 50 nmol/L increase in Lp(a)-apoB was associated with a 1.28 times higher odds ratio (OR) for coronary heart disease (CHD) compared to a 1.04 times increase for the same increment in LDL-apoB. Furthermore, a comparison using polygenic scores demonstrated that the hazard ratio (HR) for CHD per 50 nmol/L increase in apoB was significantly higher for the Lp(a) cluster (1.47) than for the LDL cluster (1.04), suggesting that Lp(a) is approximately 6.6 times more atherogenic than LDL on a per-particle basis.
Implications for Practice: These findings highlight the substantial atherogenic potential of Lp(a) compared to LDL, indicating that Lp(a) should be a key focus for drug intervention strategies in populations at risk for CHD. The marked difference in atherogenicity underscores the importance of targeted treatments and monitoring for individuals with elevated Lp(a) levels.

Clinical validation of a cell-free DNA test for colorectal cancer screening: sensitivity and specificity analysis
20 Mar, 2024 | 19:16h | UTCStudy Design and Population: This study conducted a clinical validation of a cell-free DNA (cfDNA) blood-based test to screen for colorectal cancer in a cohort of 10,258 individuals, 7,861 of whom met the eligibility criteria and were evaluable. The research aimed to assess the test’s performance by comparing its sensitivity for detecting colorectal cancer and its specificity for identifying advanced neoplasia (including colorectal cancer or advanced precancerous lesions) against the outcomes of screening colonoscopy, a standard procedure.
Main Findings: The cfDNA test demonstrated a sensitivity of 83.1% for detecting colorectal cancer, with stage-specific sensitivities of 87.5% for stages I-III cancers. However, its sensitivity for identifying advanced precancerous lesions was notably lower at 13.2%. On the specificity front, the test showed an 89.6% ability to correctly identify individuals without any advanced colorectal neoplasia and had an overall specificity of 89.9% for those with a negative colonoscopy result, indicating no presence of colorectal cancer, advanced precancerous lesions, or non-advanced precancerous lesions.
Implications for Practice: The cfDNA blood-based test presents a promising tool for colorectal cancer screening, boasting substantial sensitivity for colorectal cancer detection and high specificity for advanced neoplasia. Its non-invasive nature could potentially enhance screening adherence, facilitating earlier cancer detection and possibly reducing colorectal cancer-related mortality. However, the test’s low sensitivity for advanced precancerous lesions suggests a need for further research and development to improve early detection capabilities.

RCT: Effectiveness of mechanical and oral antibiotic bowel preparation in reducing postoperative complications in elective rectal resection
20 Mar, 2024 | 18:18h | UTCStudy Design and Population
This double-blind, placebo-controlled randomized clinical trial was conducted at three university hospitals in Finland, involving 565 patients aged 18 years and older undergoing elective rectal resection with primary anastomosis for tumors 15 cm or less from the anal verge, as determined by magnetic resonance imaging. Participants were allocated in a 1:1 ratio to either the mechanical and oral antibiotic bowel preparation (MOABP) group, receiving neomycin and metronidazole orally, or to the mechanical bowel preparation (MBP) plus placebo group, with all interventions occurring the day before surgery alongside standard preoperative intravenous antibiotics.
Main Findings
The study found that patients in the MOABP group experienced significantly fewer postoperative complications, with a median Comprehensive Complication Index significantly lower than that of the MBP plus placebo group. Additionally, the MOABP group showed reduced rates of surgical site infections (SSIs) and anastomotic dehiscence compared to the control group, demonstrating a clear benefit in postoperative outcomes.
Implications for Practice
The results of this trial suggest that incorporating oral antibiotics with mechanical bowel preparation prior to elective rectal resection significantly reduces postoperative complications, including SSIs and anastomotic dehiscence. Therefore, MOABP should be adopted as the standard regimen for patients undergoing these procedures to improve postoperative outcomes and reduce the burden of complications. This evidence underscores the importance of updating surgical protocols to include this preparation strategy.

RCT: Quadruple quarter-dose hypertension medication versus monotherapy for ambulatory blood pressure control
20 Mar, 2024 | 18:00h | UTCStudy Design and Population: This randomized clinical trial investigated the efficacy of a combination of four ultra-low-dose blood pressure medications (quadpill) compared to standard monotherapy in adults with hypertension. A total of 591 participants, either untreated or currently on monotherapy for hypertension, were enrolled and randomly assigned to receive either the quadpill (irbesartan 37.5 mg, amlodipine 1.25 mg, indapamide 0.625 mg, and bisoprolol 2.5 mg) or a monotherapy control (irbesartan 150 mg).
Main Findings: At 12 weeks, the quadpill group demonstrated significantly lower mean 24-hour ambulatory systolic and diastolic blood pressure (SBP and DBP) by 7.7 mmHg and 5.3 mmHg, respectively, compared to the monotherapy group, with similar reductions observed during daytime and night-time. Additionally, the rate of blood pressure control (24-hour average BP < 130/80 mmHg) was significantly higher in the quadpill group (77% vs. 50%). The study highlighted the quadpill’s effectiveness in reducing blood pressure variability and enhancing control rates across a 24-hour period.
Implications for Practice: The findings from this study support the superior efficacy of an ultra-low-dose quadruple medication strategy over monotherapy in managing ambulatory blood pressure among hypertensive patients. These results suggest that a quadpill approach could offer a more effective means for clinicians to achieve and maintain blood pressure control in hypertensive patients, potentially improving cardiovascular outcomes.

Meta-Analysis: Efficacy of exercise modalities in major depressive disorder treatment
20 Mar, 2024 | 17:54h | UTCStudy Design and Population: This article presents a systematic review and network meta-analysis of randomized controlled trials to assess the optimal dose and modality of exercise for treating major depressive disorder, comparing its effects to psychotherapy, antidepressants, and control conditions such as usual care or placebo. The review included 218 unique studies encompassing 495 arms with a total of 14,170 participants who met the clinical cutoffs for major depression.
Main Findings: The findings revealed moderate reductions in depression symptoms for several exercise modalities when compared to active controls. Notably, walking or jogging, yoga, and strength training demonstrated the most significant effects. The effectiveness of exercise was found to be proportional to the intensity of the activity prescribed. Among these, yoga and strength training were identified as the most acceptable modalities for participants. However, the overall confidence in these results is low due to the high risk of bias in the included studies, with only one study meeting the criteria for a low risk of bias.
Implications for Practice: The study concludes that exercise, particularly walking or jogging, yoga, and strength training at sufficient intensities, can be an effective treatment for major depressive disorder. These modalities could be recommended alongside traditional treatments such as psychotherapy and antidepressants. Future research should focus on blinding participants and staff to mitigate expectancy effects and improve the reliability of findings. The inclusivity of exercise as a core treatment for depression could significantly impact treatment strategies and patient outcomes.

Phase 2 RCT: Low-dose aspirin significantly reduces hepatic fat in MASLD patients without cirrhosis
20 Mar, 2024 | 17:48h | UTCStudy Design and Population: This phase 2, randomized, double-blind, placebo-controlled clinical trial was carried out over six months at a single hospital in Boston, Massachusetts. The study included 80 participants aged 18 to 70 years diagnosed with metabolic dysfunction–associated steatotic liver disease (MASLD) but without cirrhosis. Participants were randomly assigned to receive either 81 mg of daily aspirin (n=40) or placebo (n=40).
Main Findings: The trial revealed that aspirin significantly reduced the mean absolute change in hepatic fat content by -10.2% compared with placebo, as measured by proton magnetic resonance spectroscopy (MRS), with a statistically significant difference (P=0.009). Furthermore, aspirin treatment notably decreased relative hepatic fat content, increased the proportion of patients achieving a 30% or greater reduction in hepatic fat, and reduced both absolute and relative hepatic fat content as assessed by magnetic resonance imaging proton density fat fraction (MRI-PDFF). Adverse events were mostly minor, with upper respiratory infections and arthralgias being the most common.
Implications for Practice: These findings suggest that low-dose aspirin may be an effective intervention for reducing liver fat in adults with MASLD without cirrhosis, potentially offering a simple, accessible treatment option. However, the results are preliminary and call for further confirmation in larger, more diverse populations. The study underscores the importance of considering low-dose aspirin as part of management strategies for MASLD, pending further research.

Prospective Study: Enhanced detection of colorectal cancer and precancerous lesions with next-generation stool DNA testing
20 Mar, 2024 | 17:41h | UTCStudy Design and Population:
This prospective study evaluated the efficacy of a next-generation multitarget stool DNA test for colorectal cancer screening in asymptomatic adults aged 40 and older. The study encompassed 20,176 participants undergoing screening colonoscopy to determine the test’s sensitivity and specificity in detecting colorectal cancer and advanced neoplasia, including advanced precancerous lesions.
Main Findings:
The next-generation stool DNA test demonstrated a sensitivity of 93.9% for detecting colorectal cancer and a specificity of 90.6% for advanced neoplasia, significantly outperforming the fecal immunochemical test (FIT) in sensitivity for both colorectal cancer and advanced precancerous lesions. However, the test showed slightly lower specificity for advanced neoplasia compared to FIT. No adverse events were reported, indicating the test’s safety for screening purposes.
Implications for Practice:
The findings suggest that the next-generation multitarget stool DNA test offers a superior option for colorectal cancer screening, with significantly higher sensitivity for detecting cancer and advanced precancerous lesions than the currently available FIT. This advance in non-invasive screening technology could lead to earlier detection and treatment of colorectal cancer, potentially improving patient outcomes. Further research may focus on optimizing the balance between sensitivity and specificity to enhance the clinical utility of stool DNA testing.
